Mid-Ohio Sports Car Course

Lexington, Ohio · 3.61 km · 2.25 mi · clockwise

Mid-Ohio Sports Car Course in Lexington, Ohio is a 3,614 m (2.25 mi) clockwise circuit with twelve modeled corners. Elevation in the source geometry runs from 397.4 m to 439 m — a 41.6 m (136 ft) spread, with 52.2 m of total climbing per lap. The simulated speed profile splits the lap cleanly in two: the fastest cornering comes in the middle, where Turn 7's 83 m effective radius lets the model carry a 112 km/h (70 mph) minimum, while the opening of the lap — Turns 1 through 5 — is a sustained slow section with minimums between 65 and 86 km/h (40–53 mph). One of the hardest decelerations arrives at Turn 10, the Carousel, where the simulation peaks at 129 km/h (80 mph) before shedding more than 60 km/h. Simulated lap estimates: 99.1 s for a liter bike (130 km/h / 81 mph average), 99.6 s for a Supersport 600, and 101.8 s for a middleweight 650 twin.

The Keyhole opens the lap: a 180 m right-hander on a 34.3 m effective radius that falls 4.5 m from entry to exit. In the simulation, all three bike classes arrive at essentially the same speed — about 111 km/h (69 mph) — because the corner sits early in the lap, but braking points diverge modestly with machine weight and power: the model starts braking 78 m out on the liter bike, 75 m on the Supersport 600, and only 72 m on the 650 twin. Minimum speed is identical across classes at 72 km/h (45 mph), and the exit builds back to roughly 116 km/h (72 mph), or 114 km/h (71 mph) for the twin. The downhill grade slightly reduces braking authority in the model, which is part of why the brake zones here are among the longest on the circuit. Physics-simulation estimates.

Turn 11 is an 84 m left on a 72 m radius, far more open than the Carousel it follows, descending 1 m. The simulation enters at 123 km/h (76 mph) with braking starting 66 m before the corner on the Supersport 600, 36 m out on the twin, and not at all on the liter bike, and holds a 104 km/h (65 mph) minimum — comfortably above the lap's slow-speed band before the run home. Exit speed is 124 km/h (77 mph) for the fours, 122 km/h (76 mph) for the twin. In the modeled speed profile this corner sets up the launch into Turn 12, so the exit figure here directly seeds the run onto the front straight. Physics-simulation estimates.

Turn 12 closes the lap: a 180 m left on a 65 m effective radius, climbing 2.4 m onto the front straight. The simulation carries 128 km/h (80 mph) to the brake point — among the highest corner-entry speeds on the circuit, 93 m out on the Supersport 600, 117 m on the liter bike, 63 m on the twin — and only drops to a 99 km/h (62 mph) minimum, 34 km/h faster than the lap's slowest point. Exit speed is 160 km/h (99 mph), with the twin at 156 km/h (97 mph). Because the exit feeds the longest acceleration zone of the lap, this is where the per-class power differences translate most directly into the simulated lap-time gaps. Physics-simulation estimates.
